ok so my series 2 has been throwing little tantrums over the last week...

randomly on my way to belmont one night when it was pissing with rain my car decided to start a serious rough idle, slight surging, misfiring and wanting to stall - its an auto. the car would completely drop revvs then instantly shoot back up to over 1k... massive black plumes of smoke coming out the back. went on for about 30 mins then cleared its self up... its continued doing this even after 4 tanks of fuel because im getting maybe 250km outta the tank atm cause of its hissy fits....

checked air leak - found a leak parts on order

spark plugs only 2 months old.

fuel pressure regulator - possible and requiring new one!

coil packs - only done about 100k but still stock so could be?

so i was told take off the cover where the coil packs were cause if they are getting too hot it could be causing these issues... so i attempted myself unaware that bulk shit needs to come off to remove such a simple little thing.... got half way through it yesterday, storm came through so i packed it up to tackle later. last night go to put car back together. achieved. feeling proud as punch.... go to start car FAIL... initially nothing at all but power. fiddled with stuff. car will crank but not fire like there is no fuel BUT i got half a tank FML....

IF ANYONE KNOWS OR CAN HELP ITS GREATLY APPRECIATED!!!

otherwise i might roll it out into the street and burn it lol

Start by looking at what you took off/unpluged and make sure its all back to gether correctly.

Sounds like the coil pack harness is not plugged in correctly. If you car is stock or close to it removing the cover can cause more harm than good by letting crap into that area.

From what you have described it sounds like you Air Flow Meter (AFM) is at fault. Search here and google that will give heaps of things to try and fix it.

easy to tell before pulling it apart, does it prime?

turn the key to on (not start) and see if you can here it or is there pressure in the line (squeeze it near the reg)

Just because an electrical plug looks to be connected doent mean it is. Every plug you touch go back unplug, check if there is anything in it and plug it back in makeing sure it hits home.

Similar thing happened to me with an aftermarket bonnet, water got under the coilpack covers in heavy rain and car dropped down to 5 cyl, then 4 cyl and then it didn't run. Had to pull it all apart and take out the coilpacks and clean it all out and I sold the bonnet which was a shame cause I really liked it. While the car was running on 5 cyl etc I used a hell of a lot of fuel and eventually realised that my o2 sensor had burned out too. I could only travel about 300kms on a tank of gas. Unsure if the two problems were related, but they happened at the same time. Hope that helps.

      R34 gtt rb25det neo timing belt kit

      By drifter17a · Posted

      So now doing the change and first time dealing with rb so little nervous giving engine power and potential for screwing it up When you align all marks and then remove crank bolt, timing move little I assume you can put the bolt back in once you have removed the pully to get timing to where you want?   here is pic of my both intake and exchust cam aligned, depending on angle you look they seem to be either aligned or a half tooth or so out. Any thoughts? Should you angle your face and look at each mark that way as if looking straight rather than from above as it can be misleading   <a href="https://ibb.co/ZpnhcvbF"><img src="https://i.ibb.co/HfWrGR9b/IMG-4447.jpg" alt="IMG-4447" border="0"></a> <a href="https://ibb.co/4wm2wn4q"><img src="https://i.ibb.co/JWBqWwr1/IMG-4445.jpg" alt="IMG-4445" border="0"></a>   https://ibb.co/ZpnhcvbF https://ibb.co/4wm2wn4q

      braided lines for the turbos

      By sunsetR33 · Posted

      Thanks for the reply @GTSBoy Haven't really thought of that yet, but you are right. If the hose was damaged it should be absolutely pissing by now. I'll put some heat sleeve around it for good measure since I'm already removing the line anyway.  Maybe I'll put on some of the stock hardlines if I ever fully remove the turbos again. Maybe when T51R modding the compressor housings? Might be a fun mod on GT28s for that "fake single turbo" effect.

      Unpeeling the Orange

      Update 1: I did some work on the car already before finalizing this post and my "issues" list. I dropped the Tomei exhaust in favor of the HKS Hi Power Silent. Sounds nice and I can actually hear myself think now. Also gives me a realistic chance to legally drive without silencer inserts. A bit of cheating was necessary to still be able to mount the Top Secret style diffuser. Some malusage of washers and a bit of "convincing" toward the brackets and exhaust hanger seemed to do the trick. The shaky steering wheel has been resolved as various suspension components were worn, like sway bar bushings and link bars. Most notably the two steering tie rod ends. Had some trouble finding bushings because my sway bars are not OEM thickness, 23.x up front and 27 rear. But non adjustable, so no aftermarket I suppose. Maybe they are nismo units? Turbo oil drain hoses were definitely still the originals and are new now. Wasn't the cause of the turbo oil leak sadly. Currently removing the rear turbo because of it, I suspect the braided oil feed line is the culprit. This issue needs to be dealt with so I can work towards actually getting the turbo setup legal and inspected. Two new issues to add to the list as well. Rear Main seal is probably leaking. Time will show how bad it is, I don't really want to drop the gearbox right now just for the stupid seal. Could fix a few other things in one go once I do that. Front right driveshaft grease is going past the cv boot, so at some point I'll fix that too.

Iam planing to do bigbox or BMW tranny..

      You're probably right about that one. Thanks for your suggestions, I hope I don't need a new 3rd brake light. Although wiring issues might arguably be worse. Right now I'm in the midst of a turbo removal because of my oil leak, other problems are going to have to wait for now.
